RonR

Hey Ron! I just bought an used Cobalt 2 with allegedly very little use. Problem is that at first you had to push hard the right button for it to take input compared to the other buttons which are super sensitive to touch. Now that button just wont work any more. Is there an easy fix for this or would I have to replace some parts? I am in Costa Rica and haven't found any Atomics dealer here. Thanks a lot!

I own an atomic cobalt version 1. I have had issues with the dive log incorrectly reflecting actual dive info. Today I dove to 100 feet; my cobalt showed 100’ as did my other (Suunto) computer as did the computer of my dive master. Yet after my dive the cobalt showed a max depth of 63 feet. Also it listed a second dive today which I did not make. What should I do?

RonR- I have a Cobalt w that is dead and won't charge. Tried a cold boot. Can you help ?

Hi, I have a cobalt 2, which after only 4 dives won't start a new dive. Screen displays tank pressure and depth but doesn't go into dive mode once under water. Any help welcomed.

Ron, I tried to flash my Cobalt 2 but it wouldn't take the flash so I tried the bootloader method, the screen went black. Now I can not get the computer to doing anything, it won't turn on. I would like to unplug and then re-plug in the battery to try a restart that way but I don't see how to unplug the battery. Can you tell or show me how?

I've seen that you may have a solution on how to delete the dive LOG on a cobalt computer.. could I ask you for that information as well.. I have 2 corrupt dives and I cant download past those dive.. thank you for your help.. freddydunaway@yahoo.com

Ron, I guess you're the Cobalt 2 Guru and for that, I thank you. Got a bit of a problem. My battery ran completely dead. Now it will not charge or turn on (not sure which). I did the manual reset and the bootloader window came up as expected. I copied the latest firmware file into the bootloader directory and ejected the device. Nothing. Can you suggest anything? Thanks in advance!

Dear Ron,

I hope this post finds you well.

I understand you are the go to person for Cobalt troubleshooting.

In short, the compass has disappeared on my cobalt 2 screen. When I press the button it will let me set bearings such as 90, 180 etc, however no compass appears. I have updated the firmware and restarted the unit. I am now at a loss as to what more I can do. Any insight would be much appreciated.

Regards

Hey Ron, Cobalt 1 is black screen on failed firmware update. Hung forever and now nothing. May I have battery removal instructions please. Thank you!

Dear Ron, no doubt you did answered that many times. Can I get some instructions how to fully reset divelog in Cobalt2. I need to pass the device to another person. Thank you!
